MACHINE FOR GLAMPING- COVERS 0N RECEPTACLES.

Specication of Letters Patent.

Patented Jan. 31, 1911..

Application iiled October 19, 1910. VSerial No. 587,908.

fastening covers to bottles, jars and receptacles and it consists essentiallyof a series of levers which are adapted to be operated to clamp the lower portion of the cover into a groove located at' the outer mouth of the bottle.

The levers are swingingly mounted 'on a sliding sleeve which is Operated by means of a series of detents. These levers are actuated by means of a cam disk fastened to the plunger. The plunger when operated swings the lower ends of the levers toward the neck of the bottle, and at the same time the detents are Oscillated to lift the levers into engagement with the annular groove formed in the neck of the bottle.

The n ovel features of the invention are more fully described in the following speciiication and claims and illustratedl in the accompanying drawings, in which:

Figure l represents a sectional front elevation of a machine embodying this invention.

Fig. 4 is a similar section showing the plunger pressed down and the levers in action. Fig. 5, isla horizontal section Jin the plane w Fig. 3.

In this drawing the letter a designates a frame to which is fulcrumed at b a lever cl having a handle whereby the lever can be operated. To this lever is linked a crosshead d of suitable construction to slide within the frame when the lever is operat d.

A spring e moves the cross-head and t e lever back to their originalposition. This cross-head has fastened to it a series of plungers f and these plungers are all op` mounted a sleeve j to which is fulcrumed at k a series of levers m.- These levers have cam shaped upper ends and their lower ends `part of the` i Fig. 2 isa sidel elevation thereof.l Flg. 3 1s a vertical section of a plunger.'

are preferably hook shaped to fit into the groove formed in the bottle neck. The cam shaped upper ends of the levers are adapted' at certain times tO co-act with a disklike concentric cam n fixed to the plunger.

On the upper part or stem portion of the buffer z' is ivoted a series of detents 0. The noses o each detent being in engagement with the lower end of the plunger and with the bottom portion of the sliding sleeve. A spring p is housed between the sliding sleeve and the stem of the plunger. A series of springs g are fastened to the lower part of the sliding sleeve j and their free ends engage the levers m. These springs tend to press the upper part of the levers against the disk cam n and thus spread the lower hook shapedportion of the levers.

It will be seen that when the device is in operation as shown in Fig. 4, and the plungeris pressed downward the detents 0 will be actuated by the downwardmovement of the plunger and the outer nose of each `detent will strike on to the lower portion of the sleeve j and lift' the same. At the same time cam n engages the upper cam portion of the levers m and swings the lower ends of the levers inwardly to contact with the side of a bottle,` the downward movement of the plunger then actuates the detents tolift the levers and the hook shaped portions will engage the groove formed in the bott-lez When the plunger is released as shownfin Fig. 3, the spring p will'move the sleeve j downwardly, thus oscillating the detents o to their initial positions. The pin and slot connection between the buffer z' and the plunger, allows the lunger to be moved independently and t e spring -p forms a yielding connection between these parts.- v

-I claim 1. In a bottle capping machine, the com-,

bination vwith a plunger of a sleeve slidingly mounted thereon, ay series of levers pivoted to the sleeve', mechanism for operating the plunger, and a device on the plunger for swinging the levers, a'bufer connected to the plunger, devices carried by the buffer and operated by the plunger for llfting the levers.

2. Ina bottle capping machine, the combination with a plunger of a sleeve mounted. thereon, a lseries of levers pivotedv to the sleeve, mechanism for operating the plunger and a device on the plungerA for swinging the levers, a buffer connected to the plunger, de- .vices carried by the buifer and operatively connected to the plunger mechanism for lifting the levers.

3. In a. bottle capping machine, the conbination with a'plunger of a sleeve slidingly mounted thereon, a .series of levers pivoted to the sleeve, mechanism for operating the plunger, and a camrxed to the plunger for swinging the levers, a buii'er connected to the plunger and devices pivoted tothe buer and oscillated b the plunger for lifting the sleeve with the evers. p

4. In a bottle capping machine, the combination with a plunger of a sleeve slidngly plunger for swinging the levers and oscillating the detents to lift the levers.

In testimony whereof I have hereunto set 'my hand in the witnesses.
